This CL introduces a new JSON Schema "version" dedicated to translating CRD schemas. We add all the relevant keywords but leave most of them as TODOs. We implement some of the easier checks but leave harder ones (structural schema checking, for example) for later. The main short-term TODO is support for `x-kubernetes-embedded-resource`, as most other things are less strict than needed currently, so can be punted for now.
